The physics of 16 uncoupled pendulums

Water vapour is the ultimate life support mechanism on our blue-green dot. It provides up to 70% of atmospheric heat retention, reaching concentrations of 40,000 ppm. Contrast this with CO₂ at only 420 ppm—just 4 molecules in every 10,000. Is CO₂ really the climate control

Japanese engineers developed a “Sword Tip Visualization System” for the Fencing World Championships, and it makes fencing look absolutely incredible to watch.

When you look at the spikes on a million-year chart, you see the Milankovitch cycles in action. Most of the last 100,000 years were spent under massive ice sheets. The Holocene (our current interglacial) is the thin sliver of stability that allowed human civilisation to take

You can smell rain better than a shark can smell blood. 200,000 times better. Your nose picks up the compound behind petrichor (that smell after rain) at levels so tiny it's like finding one teaspoon spilled across 200 Olympic swimming pools. That compound is called geosmin. It

1890: rinderpest arrives in East Africa. The Serengeti wildebeest collapse from over a million to 200,000. Ecologists expect the grassland to flourish. Fewer mouths, more grass. Obvious. The grassland goes backwards. 1960s: vaccination clears rinderpest from cattle. The wild

Scientist Gregg Braden warns that efforts to dramatically reduce atmospheric CO₂ could take us dangerously close to the extinction threshold, endangering all life on Earth. "If we were to meet the [the UN's climate] goals... we would see a CO₂ level right around 220 or so

Andrew Huberman described the worst morning routine in five steps. Stay in bed, recline, skip sunlight, drink coffee too early, multitask. Every one of them targets the same 30-minute neural event. Between minute 0 and 60 after waking, your body runs the cortisol awakening
